The Dillon Rifle Company DRC556 GOV in Black is the no-frills version of Dillon's 5.56 suppressor: a smooth, clean exterior with no logo texture, finished in black Cerakote. It's the look many duty, training and professional users prefer, and it's easy to wipe down and fit with a cover.
Performance is the same as the patterned DRC556. It's printed in one solid piece of Inconel 718, it's 5.375" long, and it uses Dillon's patented PIP venting to cut the back pressure that makes most AR-15 suppressors run dirty. That keeps the gun cleaner and more reliable through long range days, and the Inconel body handles the heat of high round counts.
Dillon Rifle Company designs and builds its suppressors in Phoenix, Arizona, about a half hour from our Mesa shop, so this is a locally made can you can see and buy in person.
